' asits special object the provision of means whereby the lid or cover may be securedor disengagedtrom the edges of the vessel in an easy andefi'ective manner. I

x 1h further object is to provide a 11d having a plurality of perforations, and a shutter whereby said perforations may be opened and clomd, either partially or wholly at will. 'lhese and other like objects are attained by the novel construction and combination oi parts hereinafter described and shown in the-accompanying drawings, torrnlng a material part or this disclosure, and in which- Figure l is a perspectlve view showlng a conventional type of boiler and indicating the application of the invention.

l ig. 2 is a vertical sectional view taken through the center of the same, and

Fig. 3 is a similar vertical sectional view taken on line 8-43 of ll ig'. 1.

Throughout the several drawings the nu nieral l indicatesa boiler or vessel, here shown or conventional type used in boiling articles in the process of laundrying, cornprising vertical parallel side walls, an nnperforate bottom and rounded ends the upper edges of the boiler walls having an out" turned beading ll as usual.

Adapted to lit closely over the level top ol the boiler is a domed lid or cover 12, having ext/ending marginal edges it and containing a plurality of openings over which is pivoted, on a pin it, a cover plate l'l the same having a plurality of pattern tions 18, alinable with the openings 15, the

cover plate ll, being provided with an errtending knob lQ b-y which it may be aotu- V a ably engaged with said cylindrical eatenated lEirtending downward, near tlteends oil "it claim as new and desire to secure by lhetters Patent 1sa the cover 12, are lugs close to the ends and slldably engaged therein are relatively flexible bent rods 21 terminating at their outer ends in hooks 22 adapted to engage with the exterior of the heading Ill.

The inner ends of the bent rods, which conforrn closely to the interior or the cover lQ are yolned together by a yoke 2%, from whlch rises a central rod 25, the same passing upward through a covered cylindrical element 26 which is secured to the cover l2, and in which are the ends 2? oi the bent rods 22 These ends terminate against the cover 28 of the cylindrical element 26, over which is (llSPOSGCl a casing 30 from which. the'rod extends, the rod being provided with an enlarged head 32 so that as the outer casing is raised, the rod is raised with it, coin pressing the'spring 32-3 and obviously when the outer casing 30 is depressed the rods 21 will. be elongated so as to release the hoolts tilt till
